Resin composition for powder coating, powder coating, and coated article therewith

摘要

A resin composition for a powder coating, which comprises a non-crystalline polyester resin (A) having a carboxyl group, a crystalline polyester polyurethane resin (B) and a curing agent (C) made of a compound having a functional group reactable with the carboxyl group as an essential component, yields a powder coating which is highly suitable for practical use, the powder coating having superior storage stability (blocking resistance) and forming a coating film having superior smoothness under low temperature curing conditions.
